Two soap bubbles combine to form a single bubble. In this process, the change in volume and surface area are respectively V and A $.$ If P is the atmospheric pressure, and T is the surface tension of the soap solution, which of the following relation is true.

$($A$)4PV+3TA=0$

$($B$)3PV-3TA=0$

$($C$)4PV-3TA=0$

$($D$)3PV+4TA=0$
